The towel rolls processed by such a system are then preferably used in towel dispensers, which may be of the type set forth in the copending application Ser. No. 727,157 of Robert I... Steiner and Erwin B. Bahnsen, filed May 7, 1968, now US. Pat. No. 3,502,383, and assigned to the assignee of the present invention.

A towel ironer, generally designated by the number 60, for use with the winding machine 100 of the present invention, is illustrated in FIG. 12 of the drawings, the ironer 60 being adapted to receive a wet elongated towel web 50 from an assocated washing machine (not shown), to iron the towel web 50 and then to feed it to the associated winding machine 100 of the present invention for winding into a towel roll 55. The ironer 60 includes a beater 61 being substantially triangular in transverse cross section and being rotatable in a counterclockwise direction as viewed in FIG. 12, a guide bar 62 and a towel breaker member 63. The towel web 60 is threaded over the beater 61 and around the guide bar 62 and over the breaker 63 to a conveyor 70. The conveyor 70 is disposed substantially horizontally and includes a drive roll 71, an idler roll 72 and an endless conveyor belt 73 extending therebetween for conveying the towel web 50 from the breaker member 63 to a steam chest, generally designated by the numeral 80. The steam chest 80 is hollow and includes an encompassing wall 81 having a flat bottom 82 and a convoluted top 83 forming a plurality of alternating ridges 84 and valleys 85. A plurality of pinch rolls 90 are respectively disposed in the valleys 85 of the steam chest 80, each of the pinch rolls 90 being shaped and dimensioned complementary to the associated valley 85 of the steam chest 80 and being held therein under the controlled pressure of a spring-loading apparatus (not shown). Each of the rolls 90 is rotatable counterclockwise about a shaft 91 for moving the towel web 50 from left to right as viewed in FIG. 12. Thus, the towel web 50 is fed from the associated washing machine over the beater 61 and roll 62 and breaker 63 for removing folds and excess water from the towel web 50, and thence via the conveyor to the steam chest 80. The towel web 50 is then fed between the pinch rolls 90 and the upper wall 83 of the steam chest from left to right along the steam chest 80 and then is discharged from the right-hand end thereof. The action of the heat provided by the steam chest 80 and the compression provided between the rollers and the steam chest 80 combine to iron the towel web 50 for removing wrinkles therefrom in a well-known manner.

The towel winding machine includes a feed assembly comprising a transfer conveyor 101 and a feed conveyor 105, mounted on a supporting framework 101a. The transfer conveyor 101 is disposed susbstantially horizontally beneath the steam chest 80 and includes a drive roll 102 disposed immediately beneath the right-hand end of the steam chest 80, and an idler roll 103 disposed forwardly of the drive roll 102 and an endless conveyor belt 104 connecting the drive roll 102 to the idler roll 103. The transfer conveyor belt 104 moves in a clockwise direction as viewed in FIG. 13 and preferably has a surface speed approximately 40 percent greater than the surface speed of the towel web 50 as it is fed from the ironer 60, whereby the towel web 50 may be fed from the ironer 60 by the transfer conveyor 101 to the right as viewed in FIG. 13 without folding upon the transfer conveyor 101.

The feed conveyor 105 is substantially longer than the transfer conveyor 101 and is inclined at an acute angle to the horizontal. The feed conveyor 105 includes a drive roll 106 at the upper end thereof rotatably mounted on a shaft 106a which is preferably supported at the opposite ends thereof in bearings on end plates 112 which are supported on the frame 101a and on a winding unit frame to be described. An idler roll 107 is disposed at the lower end of the feed conveyor 105 immediately below the idler roll 103 of the transfer conveyor 101. An endless conveyor belt 108 interconnects the drive roll 106 and the idler 107 and is driven thereby in a clockwise direction, as viewed in FIG. 13, for receiving the fed towel web 50 from the transfer conveyor 101 and feeding the towel web 50 upwardly along the feed conveyor 105 from the input end to the discharge end thereof. Thus, the transfer conveyor 101 and the feed conveyor 105 cooperate with the ironer 60 to define a first lower feed path for the towel web 50 extending from the discharge end of the ironer 60, downwardly to the transfer conveyor 101 and forwardly therealong to the feed conveyor 105 and upwardly therealong to the discharge end thereof as is clearly indicated in FIG. 13. Hereinafter the end of winding machine 100 toward the discharge end of the feed conveyor 105 will be referred to as the forward end and the end toward the input end of the feed conveyor 105 will be referred to as the rearward end.

It is an important feature of the present invention that the transfer conveyor 101 and the feed conveyor I05 and the ironer 60 associated therewith are all of sufiicient width to accommodate a plurality of towels repsectively arranged thereon in a corresponding plurality of feed lanes, each of these feed lanes having a width only slightly greater than the width of the associated towel web 50 and being arranged substantially parallel to each other in side-by-side relationship. Referring to FIG. 15 of the drawings, it will be seen that ten such feed lanes, respectively designated by the letters A to J, inclusive, have been provided in the preferred embodiment of this invention, but it will of course be recognized that the machinery of this invention may be constructed so as to accommodate any desired number of such feed lanes.

The rearward end of the plate 126 has a width substantially equal to the width of the associated feed lane, the downwardly extending wings 128 being adapted to straddle the associated towel web 50 in a manner to be described more fully hereinafter. The pivot block 115 and the shaft 1 18, guide rollers 120 and towel follower 125 coupled thereto, are all pivotally movable about the axis of the pivot pin 1 13 and the guide rollers 120 are freely rotatable about the longitudinal axis of the shaft 118, all for facilitating the feed-directing function of theassembly 110 as will be described in detail hereinafter.

Referring now to FIGS. 1 and 2 of the drawings, there is shown a forward supporting framework, generally designated by the numeral 130 and preferably formed of steel, for supporting the winding units 150 of the towel winding machine 100'. The framework 130 includes a pair of upstanding posts 131 connected at the lower ends thereof to foot plates 132 which are supported upon the floor or other supporting surface 133. lnterconnecting the posts 131 at the upper ends thereof is a tubular cross beam 135 having a substantially rectangular cross section and disposed substantially horizontally. Respectively connected to and closing the opposite ends of the tubular cross beam 135 and extending upwardly therefrom substantially normal thereto are the pair of end plates 112, the upper ends of the plates 112 supporting the opposite ends of the feed conveyor drive 106a as described above. Also, extending between the end plates 112 just forwardly of the drive roll 106 and substantially parallel thereto is a cross bar 137 for a purpose to be described more fully hereinafter. It will be noted that the end plates 112 cooperate with the hollow cross beam 135 to define therein a closed chamber 136.

Referring now also to FIGS. 7 to 9 of the drawings, there are provided a plurality of flat, relatively thin upstanding plates of different shapes, including upper support plates 140 and 1400, intermediate support plates 144 and lower support plates 147, all carried by the cross beam 135 and respectively disposed at the side boundaries of the feed lanes A to J substantially parallel to one another. More particularly, the support plate 140 lies in the vertical midplane of the winding machine 100 and separates the feed lane E from the feed lane F. The supportplate 140 is generally rectangular in shape and is provided at the upper end thereof with a forwardly and upwardly extending arm 141 having an opening in the upper end thereof for accommodating therethrough the drive shaft 106a of the feed conveyor 105. Formed in the rear edge of the support plate 140 is a right angle notch or recess 143 shaped complementary to the cross beam 135 and receiving the cross beam 135 therein, whereby the plate 140 abuts against and is welded to the front and bottom walls of the cross beam 135, all for securely supporting the mounting plate 140 on the cross beam 135. Extending vertically upwardly from the bottom edge of the support plate 140 adjacent to the front end thereof is a substantially rectangular slot 142. Disposed three lanes to either side of the support lane 141, i.e., between feed lanes 8 and C and between feed lanes H and J, are support plates 140a which are each constructed substantially identically to support plate 140 with the exception that the plates 140a are not provided with the mounting arm 141. The support plates 140a are each disposed vertically and are connected to the cross beam 135 in the same manner as is support plate 140.

Respectively disposed at the left-hand edge of feed lane A, between feed lanes C and D, between feed lanes F and G, and between feed lanes I and J, are four identically-constructed intermediate support plates 144, each of the support plates 144 being disposed parallel to the central support plate 140, but displaced a short distance downwardly and rearwardly therefrom.

The support plates 144 are all identically constructed and have an irregular shape provided at the upper rear comer thereof with a notch 146 for accommodating the cross beam 135 therein, whereby the support plates 144 are connected to the cross beam 135 by appropriate means such as welding. Extending vertically upwardly from the bottom edge of each of the support plates 144, approximately midway between the front and rear ends thereof, is a substantially rectangular slot 145. An arcuate recess 146a is formed in the top front edge of the plate 144.

Respectively disposed between the feed lanes A and B, between the feed lanes D and E, and between the feed lanes G and H, are three identically-constructed lower support plates 147, all disposed parallel to the intermediate support plates 144 but displaced downwardly and rearwardly a short distance therefrom. The support plates 147 are each provided at the upper end thereof with a notch 149 for accommodating the cross beam 135, whereby the support plates 147 are connected to the cross beam 135 by appropriate means such as welding. Extending vertically upwardly from the bottom end of each of the support plates 147, intermediate the front and rear ends thereof, is a substantially rectangular slot 148. An arcuate recess 149a is formed in the top front edge of the plate 147.

It will be noted that the support plates 140, 140a, 144 and 147 comprise a total of ten support plates, and when the support plates 140 and 140a are considered to be the same, it can be seen that these plates are arranged in an alternating pattern on the frame 130. Thus, beginning at the left-hand edge of feed lane A as viewed in FIG. 1, the plates are arranged from left to right in a repeating pattern as follows: an intermediate plate 144, a lower plate 147, an upper plate 140, an intermediate plate 144, a lower plate 147, etc., with a plate disposed at the left-hand boundary of each of the feed lanes A to J. Each cycle of this repeating pattern includes a set of three support plates, i.e., an upper support plate 140, an intermediate support plate 144 and a lower support plate 147, one of these sets of three support plates being illustrated in FIGS. 8 to 10 of the drawings. Referring to FIG. 9 it can be seen that the support plates 140 (or 140a), 144 and 147 in each set of the pattern are staggered horizontally and vertically on the frame 130 in such a manner that the upper ends of the slots 142, 145 and 148 are spaced equidistantly from one another. More particularly, the upper end of the slot 145 is disposed below and rearwardly of the upper end of the-slot 142, and the upper end of the slot 148 is disposed below and rearwardly of the upper end of the slot 145, all for a purpose to be described more fully hereinafter.

Respectively mounted on the frame 130, and more particularly on the support plates 140 (or 140a), 144 and 147, are a plurality of winding units, generally designated by the numeral 150, equal in number to the feed lanes of the winding machine 100. The winding units 150 are all of identical construction whereby only one of these units will be described in detail. Referring, for example, to FIGS. 3 through 7 of the drawings, the winding unit 150 comprises a drive motor 155, a winding mandrel 160, and an ejector unit 80. The drive motor 155 is preferably a gear head motor of the constant-torque type and is provided with a generally cylindrical motor housing 151 and a generally cylindrical gear head housing 152 connected to the motor housing 151, with the longitudinal axis of the gear head housing 152 disposed substantially normal to the longitudinal axis of the motor housing 151. Spaced circumferentially around the right-hand end of the gear head housing 152, as viewed in FIG. 3, and extending outwardly therefrom are a plurality of mounting legs 153, connected at the outer ends thereof to a substantially circular mounting plate 154. In use, the mounting plate 154 is disposed parallel to the associated one of the support plates 140 (or 140a), 144 or 147 (a plate 144 is shown in FIG. 3) and is fastened to the left-hand side thereof (as viewed in FIG. 3) by suitable fastening means such as screws or bolts for supporting the drive motor 155 on the support plate 144. The mounting plate 154 is so oriented that the axis thereof passes through the vertical midline of the slot 145 in the support plate 144, a short distance below the upper end of the slot 145. The output shaft of the drive motor 155 is provided with a worm 156 adapted for meshing engagement with a worm gear 157 in the gear head housing 152. Connected to the opposite ends of the gear head housing 152 and coaxial therewith are a pair of bearings 158. The mandrel 160 is disposed substantially horizontally and has a cylindrical inner portion 161 (disposed to the left in FIG. 3) and an outer portion 162, the inner portion 161 extending through the slot 145 in the support plate 144, through a complementary opening centrally disposed in the mounting plate 154 and through the bearings 158 and gear head housing 152 coaxial therewith, the inner portion 161 of the mandrel 160 being coupled to the worm gear 157, whereby the mandrel 160 is rotatably driven about the longitudinal axis thereof in a counterclockwise direction as viewed in FIGS. 9 and 10. The outer portion 162 of the mandrel 160 extends to the right of the support plate 144, as viewed in FIG. 3, and is substantially hex agonal in transverse cross section, being provided with six equal outer side faces 163. The mandrel 160 is of hollow metal tubular construction and is closed by a plug 166 force fed into the free distal end 164 thereof to define an enclosed chamber 168 therein. Formed in one of the side faces 163 of the mandrel 160 are a plurality of elongated slots or openings 165 communicating with the chamber 168. j

The towel winding machine 100 is also provided with a suction pump 1.70, which is coupled by means of a connecting pipe or conduit 171 to a fitting 172 extending through one wall of the hollow cross beam 135, whereby communication is provided between the suction pump 170 and chamber 136 in the cross beam 135. A plurality of input fittings 173 equal in number to the suction effect through the openings 165 for attracting the leading end of the towel web 51]) to the mandrel 160 when the towel web 50 is fed to the vicinity of the mandrel 160 for automatically initiating the winding of the towelweb 50 on the mandrel 160. Preferably, the suction pump 170 maintains a pressure within the chamber 168 of approximately 10 inches of mercury column, it having been found that this degree of vacuum will produce a sufficient suction through the openings 165 to effectively capture the leading end. 52 of the towel web 50.

The winding unit 150 is also provided with an ejector unit, generally designated by the numeral 180, the ejec tor unit 180 preferably being fluid-actuated and including an air cylinder 181 provided with an externally threaded stud 182 at one end thereof. Threadedly engaged with the stud 182 ia an annular mounting bracket 183 which abuts against the left-hand side of the support plate 144, as viewed in FIG. 3, immediately below the drive motor mounting plate 154. The cylinder 181 is disposed substantially horizontally and is provided with a movable piston 184 therein, the right-hand end of the piston 184 being externally threaded and extendwinding units 150 are also provided through the wall of the cross beam 135. Coupled to each of the fittings 173 is a lead conduit or pipe 174 which is in turn coupled to a control valve 175, which is in turn coupled to connector 178, the connector 178 being coupled to the open inner end of the mandrel 160 by an air-tight nylon coupler 167 which permits free rotation of the mandrel 160 therein. Thus, it can be seen that the hollow cross beam 135 acts as a manifold between the suction pump 170 and the mandrels 160 of each of the winding units 150. The control valve 175 is preferably solenoidactuated, and is provided with a solenoid armature 373 and a bias spring 177, the details of operation of the control valve 175 to be described hereinafter.

When the valve 175 is open, the suction pump 17 will draw air from the chamber 168 in the mandrel 160, thereby causing an area of reduced pressure in the chamber 168 and a consequent flow of air into the chamber 168 through the openings 165 in the side of the mandrel 160. There is thus created a vacuum or ing outwardly beyond the stud 182. The longitudinal axis of the piston 184 passes through the vertical midline of the slot of the support plate 144 substantially normal thereto, with the threaded end of the piston 184 extending through the slot 145. A flat, upstanding ejector arm 185 is coupled to the piston 184, the threaded end of the piston 184 being received through a complementary opening in the ejector arm 185 and secured thereto by a nut 186. The ejector arm 185 is shaped complementary to the slot 145 in the support plate 144 and has a thickness slightly less than the thickness of the support plate 144,, whereby the ejector arm 185 may be nested within the slot 145. At the upper end of the ejector arm 185 is a circular opening 187 for accommodating the mandrel therethrough. The cylinder 181 is provided with two air inlet ports 188 and 189 adapted for coupling to a suitable source of air (not shown) for moving the piston 184 between an ejecting position illustrated in phantom in FIG. 3, and a retracted position illustrated in solid line in FIG. 3. In the ejecting position thereof, the piston 184 is fully extended to the right of the cylinder 181, with the ejector arm 185 being disposed at the free distal end 164 of the mandrel 160. When the piston 184 is in its retracted position, it is fully withdrawn into the cylinder 181 with the ejector arm 185 disposed completely within the slot 145 in the support plate 144 so as not to interfere with the winding of the towel web 50 on the mandrel 160 as will be described below.

It will be noted that the mandrel 160 has a length nearly equal to twice the width of the associated feed lane, whereby the tapered portion 162 of the mandrel extends substantially across the associated feed lane, while the cylindrical end 161 of the mandrel 160 and the drive motor 155 coupled thereto are disposed in longitudinal alignment with an adjacent feed lane, viz., the feed lane immediately to the left of the feed lane associated with the winding unit 150. In addition, it will be noted that the cylinder 181 of the ejector unit is also disposed in longitudinal alignment with the feed lane adjacent to the left-hand side of the associated feed lane. In fact, the cylinder 181 has a length greater than the length of the feed lane, whereby it extends even beyond the adjacent feed lane, as indicated, for

example, in FIG. 8. Furthermore, each of the winding units 150 is provided with a towel roll receptacle or catcher 177, which is of a wire or rod mesh construction, and is disposed beneath and immediately to the right of the free distal end 164 of the mandrel 160, as indicated in FIGS. 7 and 8. Since the mandrel 160 extends across substantially the entire width of the associated feed lane, the roll receptacle 177 is disposed in longitudinal alignment with the next adjacent feed lane to the right of the associated feed lane as viewed in FIG. 8, the receptacle 177 being supported between the support plates bordering the adjacent feed lane by means of a mounting rod 179, the receptacle 177 being tilted slightly downwardly and forwardly of the winding machine 100 and being provided with a plurality of upturned prongs 177a at the forward end thereof for retaining the associated towel roll thereon. Thus, it can be seen that while the winding unit 150 is associated with only one of the feed lanes A to J, it has an overall width substantially equal to the combined widths of three such feed lanes. For example, referring to FIG. 8, the winding unit 150 associated with feed lane G has a mandrel 160 with the tapered section 162 disposed in feed lane G, and with the cylindrical section 161 and drive motor 155 and ejector cylinder 181 disposed in alignment with feed lane F, and with the roll receptacle 177 disposed in feed lane H.

Accordingly, in order to accommodate the winding units 150 in a space having approximately the same width as the feed conveyor 105, i.e., a width substantially equal to the combined widths of the feed lanes A to J, it is necessary to stagger the winding units 150 on the frame 130. This staggering is accomplished by the staggering of the support plates 140 (or 140a), 144 and 147 described above. Considering, for example, a set of three such support plates as is set forth in FIG. 9, it will be apparent that when the winding units 150 for each of the feed lanes A to J are mounted on the support plates as described above, i.e., with the mandrel 160 and the ejector arm 185 disposed in the rectangular slot of the associated support plate, there will result a horizontal and vertical staggering of the winding units 150 wherein a winding unit 150 associated with an intermediate support plate 144 is disposed below and rearwardly of a winding unit 150 associated with an upper support plate 140 and is disposed above and forwardly of a winding unit 150 associated with a lower support plate 147. Thus, neither the drive motor 155 nor the ejector cylinder 181 nor the roll receptacle 177 of the winding unit 150 will interfere with the mandrel 160 of an adjacent winding unit 150, but all ten of the winding units 150 may be completely accommodated in a space having a width only slightly greater than the combined widths of the feed lanes A to J.

Referring to FIG. 1, it will be seen that this staggered arrangement of the winding units 150 results in a pattern wherein each of the intermediate feed lanes B to I has the mandrel 160 of the associated winding unit 150 disposed therein, with the drive motor 155 and ejector cylinder 181 of one adjacent winding unit 150 and with the roll receptacle 177 of the other adjacent winding unit 150 disposed in longitudinal alignment with the feed lane but displaced therefrom. One of the end feed lanes, i.e., feed lane J, has the mandrel 160 of the associated winding unit 150 disposed therein and has the towel roll receptacle 177 associated with the feed lane I disposed in longitudinal alignment with the feed lane J but displaced therefrom, there being no drive motor 155 in longitudinal alignment with the feed lane J. The other end feed lane, i.e., feed lane A, has the mandrel 160 of the associated winding unit disposed therein, and has the drive motor 155 associated with the feed lane B disposed in longitudinal alignment with the feed lane A but displaced therefrom, there being no roll receptacle 177 in alignment with the feed lane A. It will also be noted that the framework 130 must be slightly wider than the total width of the feed lanes A to J in order to accommodate the drive motor 155 associated with the feed land A and the roll receptacle 177 associated with the feed lane J.

Referring now to FIG. 10 of the drawings, it will be seen that when the leading end 52 of a towel 50 is fed from the discharge end of the feed conveyor it falls vertically under the force of gravity to the associated winding unit 150. Accordingly, it is desirable that the associated winding unit 150 be so positioned on the frame that the mandrel 160 will lie directly beneath the discharge end of the feed conveyor 105 so that the leading end of the associated towel web may fall directly thereupon. However, by reason of the horizontal staggering of the winding units 150 described above, only certain ones of the winding units 150 may be so positioned. As described above the winding units 150 have been arranged in three vertically spacedapart horizontal levels, an upper level including the three winding units 150 associated with the upper support plates (or 140a), an intermediate level including the four winding units associated with the intermediate support plates 144 and a lower level including the three winding units 150 associated with the lower support plates 147. The winding units 150 have been so arranged on the frame 130 that the mandrels of the upper level winding units 150 are disposed directly beneath the discharge end of' the feed conveyor 105, whereby the leading ends 52 of the associated towel webs 50 may fall directly onto these upper level mandrels 160. However, the intermediate level and the lower level mandrels 160 are displaced rearwardly of the discharge end of the feed conveyor 105, and there is therefore provided a plurality of guide chute assemblies, generally designated by the numeral 190, for respectively guiding the associated towel webs 50 to the mandrels 160 of these rearwardly displaced winding units 150.

More particularly, each of the lower level and intermediate level winding units 150 is provided with a plurality of parallel, spaced-apart curved guide rods 191 disposed in the associated feed'lane, each of the guide rods 191 being connected at the upper end thereof to the cross bar 137 and extending downwardly and rearwardly therefrom to a point above and rearwardly of the portion of the adjacent winding unit 150 aligned with the associated feed lane. Each of the intermediate level winding units 150 is provided with a curved guide chute 192 which may preferably be formed of sheet metal and extends downwardly and rearwardly from the rearward end of the associated guide rods 191, behind the towel receptacle 177 the adjacent winding unit 150 aligned with the associated feed lane, and terminating in a lower end disposed directly above the associated mandrel 160, the guide chute 192 cooperating with the associated guide rods 191 for guiding the leading end 52 of the associated towel web 50 to the mandrel 160 of the associated intermediate level winding
